Today’s board is live: the same puzzle for everyone on Earth, one attempt each. Play it, then see where you stand.
O’Block is a block puzzle with a deadline. Every day there is one board, the same for everyone on Earth, and one attempt to make it count.
Drag pieces onto the 8×8 grid. Fill a row or a column and it clears. Chain clears to grow your combo, then see where your score lands on the worldwide leaderboard. Tomorrow, a new board.
THE DAILY
One seeded puzzle per calendar day, identical everywhere. One attempt, no retries. Wednesdays add preset stones, Fridays are a 20-piece Sprint, Sundays a 40-piece Marathon. Keep the streak alive.
CLASSIC
The endless mode, with a twist that changes everything: clear lines through ink cells to charge the ink meter, then swap a piece you don’t want for the one you do. A puzzle where you earn your luck.
JOURNEY
Twelve issues, one a month. Each issue is twenty crafted levels with target cells and a fixed queue of pieces, and each brings a new twist: edges, walls, heavy pieces, a lattice, a finale. Finish with pieces to spare for three stars. Every level is solvable: by construction, not by hope. Stuck? A hint always shows a move that still wins.
NO SIGN-UP, NO NOISE
No account. No ads. No tracking. Pick a name, pick an avatar, play. A daily reminder is there if you want it, off until you say so. Your progress lives on your device, and the leaderboard sees only the name you choose.
DESIGNED, NOT DECORATED
Two colors, one serif, a blueprint grid. Light mode is blue, dark mode is orange. That is the whole palette, and it is enough.
O’COINS
Earned by clearing lines, claimed once a day in the shop, or bought. Spend them on a continue when the board fills, an undo when one move deserves taking back, or a hint in Journey. Never in The Daily: there, everyone plays by the same rules.

Pieces land where you aim them. The square a piece would drop into used to sit slightly below and to the right of the piece in your hand, so the smallest movement could throw the outline into the next column.
Placing pieces is more forgiving. A piece aimed a cell off now snaps to the nearest fit instead of being refused, the bottom row no longer needs the board dragged off-screen to reach, and a drop that genuinely has nowhere to go says so. In dark mode it says so in blue now, because the old red sat too close to the orange accent to read.
The next Journey issue can now be opened early with O’Coins, priced by the days of waiting left. Finishing the issue before it is still required, and always will be.
Clearing a line has been redrawn as a cut. The blocks go as it reaches them, and the score stays up long enough to read. The piece in your hand takes the accent color, and the outline showing where it will land now shows up properly in dark mode.
The clock now runs in The Daily and in Journey, not only in Classic. How to play lets you put the piece back and try the move again. The coin balance in the corner now opens the Shop.
